DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The following detailed description should be read with reference to the drawings, in which like elements in different drawings are identically numbered. The drawings, which are not necessarily to scale, depict exemplary embodiments for the purpose of explanation only and are not intended to limit the scope of the invention. The detailed description illustrates by way of example, not by way of limitation, the principles of the invention. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what is presently believed to be the best mode of carrying out the invention.

As used herein, the terms “about” or “approximately” for any numerical values or ranges indicate a suitable dimensional tolerance that allows the part or collection of components to function for its intended purpose as described herein. The term “prong” refers to a projecting part and the term “plate” to a flat, thin piece of material.

In general, electronic device battery holders for holding a battery with a positive pole and a negative pole (such as a coin cell battery) according to embodiments of the present invention include at least one deflectable electrically-conductive positive terminal prong with a proximal end configured for fixed electrical connection to a power circuit of an electronic device, a deflectable distal end configured to contact a positive pole of a battery operably inserted into the electronic device battery holder, and a deflectable middle portion connecting the proximal and distal ends. The electronic device battery holder also includes at least one compressible electrically-conductive negative terminal prong configured to exert a force on a battery operably inserted into the electronic device battery holder, to contact a negative pole of the battery, to securely support and hold the battery in the electronic device battery holder, and for fixed electrical connection to the power circuit of the electronic device. In addition, the at least one deflectable electrically-conductive positive terminal prong is configured to deflect during insertion of a battery therein and exert a compressive securing force on an operably inserted battery.

Electronic device battery holders according to embodiments of the present invention are beneficial in that, for example, they include a minimal number of components (thereby simplifying handling and assembly) and do not require the inclusion or use of a dedicated battery housing, plastic cover and/or battery removal ribbon. The inclusion of a minimal number of parts results in a beneficially inexpensive electronic device battery holder that can be easily incorporated into a variety of electronic devices including, for example, hand-held test meters for the determination of an analyte (e.g., glucose) in a bodily fluid sample (such as a whole blood sample) using analytical test strips. Moreover, once apprised of the present disclosure, one skilled in the art will recognize that electronic device battery holders according to embodiments of the present invention can be readily sized and/or configured to operatively hold a variety of battery types including coin cell batteries (e.g., lithium coin cell batteries), AA batteries, AAA size batteries or other suitable batteries that are generally cylindrical in shape. Embodiments of the present invention are also beneficial in that they efficiently use compression and defection forces generated by the deflectable electrically-conductive positive terminal prong(s) and the compressible electrically-conductive negative terminal prong(s) to accomplish three tasks, namely to securely hold a battery, to provide an electrical connection between an electronic device and a battery, and to release a battery.

It should be noted that for explanatory purposes and simplicity the cross-sectional depictions of FIGS. 4, 7, 8 and 9 are each an aligned combination of cross-sectional views taken along lines D-D, E-E and F-F of FIG. 3B.

Referring to FIGS. 1-9, electronic device battery holder 100 is configured for holding a battery with positive and negative poles and includes a plurality of deflectable electrically-conductive positive terminal prongs 102 (namely four deflectable electrically-conductive positive terminal prongs, each labeled 102). Each of the deflectable electrically-conductive positive terminal prongs 102 includes a proximal end 104 configured for fixed electrical connection to a power circuit (not shown) of an electronic device via the PCB, a deflectable distal end 106 configured to contact a positive pole of the CCB inserted into the electronic device battery holder; and a deflectable middle portion 108 connecting the proximal end and the distal end. Since electronic device battery holder 100 has four deflectable electrically-conductive positive terminal prongs, there are also four proximal ends 104, four deflectable distal ends 106 and four deflectable middle portions 108.

In the embodiment of FIGS. 1-4 and 6-9, the four proximal ends 104 are integrated into a single ring-shaped base. This ring-shaped base includes two chevrons 109 configured to provide for the passage of electrical wiring (not depicted in the FIGs.) on the surface of the PCB to pass underneath of the single ring-shaped base. The height (labeled “A” in FIG. 2) of the deflectable electrically-conductive positive terminal prongs can be any suitable height including, for example, a height of 5.55 mm. The total depth (labeled “B” in FIG. 3A) of the deflectable electrically-conductive positive terminal prongs 102 can be any suitable depth including, for example, a depth of 26.62 mm. The width (labeled “C” in FIG. 3A) of the deflectable electrically-conductive positive terminal prongs 102 can be any suitable width including, for example, a width of 25.04 mm.

Electronic device battery holder 100 also includes a plurality (i.e., four) compressible electrically-conductive negative terminal prongs 110 that are configured to exert a force on the CCB operably inserted into the electronic device battery holder 100 (as represented by the arrows label J in FIG. 8 and M in FIG. 9), to contact a negative pole of the CCB, to securely support and hold the battery in the electronic device battery holder, and for fixed electrical connection to the power circuit of the electronic device (not shown) via the PCB. In addition, each of the compressible electrically-conductive negative terminal prongs 110 has a proximal end 112 configured for electrical connection to a printed circuit board (PCB). In the embodiment of FIGS. 1-4 and 6-9, the four proximal ends 112 are integrated into a single ring-shaped base. Compressible electrically-conductive negative terminal prongs 110 can be configured to provide any suitable compressive force including, for example, a compressive force in the range of 100 grams-force to 200 grams-force.

In electronic device battery holders according to embodiments of the present invention including electronic device battery holder 100, the plurality of compressible electrically-conductive negative terminal prongs are configured to be disposed essentially within a boundary (e.g., a circumference) defined by at least one deflectable electrically-conductive positive terminal prong when the electronic device battery holder is attached to an electronic device. Such a configuration is most clearly evident from the top views depicted in FIGS. 6 and 8 wherein the four proximal deflectable electrically-conductive positive terminal prongs 102 form a circumference (ring) and the four compressible electrically-conductive negative terminal prongs 110 are disposed within that circumference. Since the plurality of compressible electrically-conductive negative terminal prongs are within such a circumference and also under an inserted battery (see, for example, FIG. 8), any risk of a user inadvertently creating a deleterious short circuit between the compressible electrically-conductive negative terminal prongs and the deflectable electrically-conductive positive terminal prongs during battery insertion is minimized.

In electronic device battery holder 100, deflectable electrically-conductive positive terminal prongs 102 are configured to deflect during insertion of a battery therein and exert a compressive securing force (represented by the arrows labeled I in FIG. 8) on an operably inserted CCB. This deflection is represented by the dashed lines and arrows of FIG. 7 and is enabled by the flexible properties of the material of which the deflectable electrically-conductive terminal prongs are formed. Deflectable electrically-conductive positive terminal prongs 102 can be configured to provide any suitable compressive force including, for example, a compressive force in the range of 50 grams-force to 100 grams-force.

In the embodiment of FIGS. 1-4 and 6-9, deflectable distal ends 106 each includes a hook portion 130 configured to provide an electrical contact to the positive pole of the CCB and a release surface 132 configured for a user to press (denoted by arrow K in FIG. 9), thereby defecting a deflectable distal end (depicted by arrow L of FIG. 9) and releasing the CCB (depicted by the arrow labeled N in FIG. 9). It should be noted that the force exerted by the compressible electrically-conductive negative terminal prongs 110 holds the CCB against hook portions 130 as depicted in FIG. 8 during use. Such a force can be of any suitable magnitude including a force in, for example, the range of 100 grams to 200 grams of force. Release surfaces 132 are embossed with a conical shape (see FIG. 2 in particular) to enable a user to easily use a single finger pressing motion to release a battery from electronic device battery holder 100.

Electronic device battery holders according to embodiments of the present invention can be manufactured using any suitable techniques including, for example, metal stamping and forming techniques. Deflectable electrically-conductive positive terminal prongs and compressible electrically-conductive negative terminal prongs can, for example, be made formed of predetermined configuration from a thin metal plate. Moreover, the compressible electrically-conductive negative terminal prong(s) is configured to be disposed within a circumference defined by at least one deflectable electrically-conductive positive terminal prong when the electronic device battery holder is attached to an electronic device (see, for example, FIG. 3).

Deflectable electrically-conductive positive terminal prongs and compressible electrically-conductive negative terminal prongs employed in embodiments of the present invention can be formed from any suitable materials including, for example, carbon steel, beryllium copper, stainless steel, phosphor bronze materials. In addition, the thickness of such materials can be, for example, in the range of 0.2 mm to 0.5 mm.

FIG. 10 is a flow diagram depicting stages in a method 200 for using an electronic device battery holder. Referring to FIG. 10 as well as FIG. 7 and FIG. 9, method 200 includes, at step 210 of FIG. 10, operably inserting a battery (such as a coin cell battery) into an electronic-device battery holder. The operable insertion is such that (i) at least one deflectable electrically-conductive positive terminal prong of the electronic device battery holder deflects during the insertion, exerts a compressive securing force on the operably inserted battery and contacts a positive pole of the inserted battery; and (ii) at least one compressible electrically-conductive negative terminal prong is compressed, exerts a force on the operably inserted battery (e.g., a securing force that holds the battery in the electronic device battery holder), and contacts a negative pole of the battery. See also, FIGS. 7 and 8 and their descriptions herein.

At step 220 of method 200, the operably inserted battery is released by a user depressing a release surface of the at least one deflectable electrically-conductive positive terminal prong, thereby removing the compressive securing force. The removal of the securing compressive force is such that the force of the compressible electrically-conductive negative terminal prong pushes the battery from operable insertion in the electronic device battery holder. See also, FIG. 9 and its description above.

Method 200 is beneficial in that, for example, the battery can be operably inserted by a user with a simple downward pressing motion (see arrow G of FIG. 7) and the battery is released (in the direction of arrow N in FIG. 9) using a simple downward pressing motion (in the direction of arrow K in FIG. 9) without the cumbersome use of a battery removal ribbon.

Once apprised of the present disclosure, one skilled in the art will recognize that method 200 can be readily modified to incorporate any of the techniques, benefits, features and characteristics of electronic device battery holders according to embodiments of the present invention and described herein.

While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention.
